The main questions it aims to answer are:\n\nDoes one method create more usable embryos (blastocysts) than the other?\n\nIs there a difference in how often fertilization does not happen at all?\n\nDo either of the methods lead to better embryo quality or early pregnancy?\n\nParticipants will:\n\nHave their eggs divided into two groups. One group will be fertilized using ICSI (where a sperm is injected directly into an egg), and the other using conventional IVF (where eggs are mixed with sperm in a dish).\n\nThe fertilization method for each egg will be randomly assigned, with a random process also used to determine the assignment of any extra egg when an odd number is collected.\n\nContinue regular fertility treatment while the study team compares the results of each fertilization method.\n\nThis study includes people with non-male factor infertility and uses frozen donor sperm. It hopes to learn whether ICSI, which is often used even when it may not be needed, truly helps improve outcomes compared to conventional IVF in these cases.",[26,27,28],"Infertility, Female","Reproductive Techniques, Assisted","Fertilization in Vitro",[30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48],"Intracytoplasmic Sperm Injection (ICSI)","Conventional IVF","Frozen Donor Sperm","Sibling-Oocyte Design","Non-Male Factor Infertility","Blastulation Rate","Total Fertilization Failure (TFF)","Fertilization Outcomes","Embryo Quality","Clinical Pregnancy Rate","Assisted Reproductive Technology (ART)","Embryo Development","In Vitro Fertilization","Oocyte Randomization","Female Infertility","Cryopreserved Sperm","Randomized Controlled Trial (RCT)","Reproductive Medicine","Fertility Treatment","RECRUITING","2025-09-09",{"date":52,"type":53},"2025-09-16","ACTUAL",{"date":55,"type":20},"2025-09-15",{"date":57,"type":20},"2026-05-01",{"name":59,"class":60},"Shady Grove Fertility Reproductive Science Center","OTHER"]
